When you attach more than five photos to an email on an iPhone or iPad, Mail automatically converts each photo into a separate attachment instead of embedding them in the message body. This guide shows you how to send 10, 20, or even 100 photos at once, using the built-in Mail app or the Files app, without any third-party tools.
What You’ll Need
- An iPhone or iPad running iOS 13 or later (the steps are nearly identical on older versions)
- The Mail app (preinstalled) or any email account set up in Settings > Mail
- Photos stored in the Photos app or in the Files app
- A stable internet connection for uploading large attachments
Step-by-Step
Method 1: Using the Photos App (Fastest for a Handful of Photos)
- Open the Photos app on your iPhone or iPad.
- Tap Select in the top-right corner.
- Tap each photo you want to send. A blue checkmark appears on each selected photo. You can drag your finger across multiple photos to select them quickly.
- Tap the Share button (the square with an arrow pointing up) at the bottom-left.
- From the share sheet, tap the Mail icon (it looks like an envelope). If you don’t see it, scroll right in the app row and tap More to add it.
- Mail opens with a new message. The photos are attached as small thumbnails at the bottom of the email body.
- Enter the recipient’s email address, a subject, and any message text.
- Tap Send (the paper airplane icon) in the top-right corner.
Method 2: Using the Files App (Best for Large Batches or HEIC Files)
- Open the Files app (the blue folder icon).
- Navigate to On My iPhone or iCloud Drive.
- If your photos are not already in Files, you need to export them first:
- Go to Photos, select the photos, tap Share, then choose Save to Files.
- Pick a folder (e.g., On My iPhone > Downloads) and tap Save.
- In Files, tap Select in the top-right corner.
- Tap each photo file you want to attach. You can also tap and drag to select a range.
- Tap the Share button at the bottom.
- Choose Mail from the share sheet.
- Mail opens with all selected files attached as separate attachments (they appear as file icons, not thumbnails).
- Fill in the recipient, subject, and message, then tap Send.
Method 3: Compress Photos First (For Very Large Batches)
- If you’re sending more than 20 photos or very high-resolution images, consider making a ZIP file first.
- In the Files app, select all the photos you want to send.
- Tap the More button (three dots in a circle) at the bottom-right.
- Tap Compress. This creates a single .zip file containing all photos.
- Select that .zip file, tap Share, then choose Mail. The recipient can unzip it on their end.
Common Mistakes
- Selecting photos in the email composer instead of Photos: When you tap the camera icon inside a new email, you can only attach one photo at a time. Always start from the Photos or Files app.
- Forgetting that Mail compresses photos: By default, Mail asks if you want to resize photos when you attach them. If you choose “Large,” the recipient gets a compressed version, not the original full-resolution file.
- Selecting photos from iCloud Photos that aren’t downloaded: If your photos are in iCloud and not stored on the device, Mail may fail to attach them. Make sure they are downloaded to your device first (tap the cloud icon in Photos to download).
- Hitting the attachment size limit: Most email providers (Gmail, Yahoo, Outlook) cap attachments at 25 MB per email. If your photos exceed this, the email will fail to send.
Tips
- Use “Actual Size” for originals: When Mail asks about image size, choose Actual Size if you want to send the full-resolution file. Choose Large or Medium to reduce file size and speed up sending.
- Send a link instead: For more than 25 photos, consider using iCloud Photo Sharing (create a shared album and invite the recipient) or a cloud storage service like Dropbox or Google Drive. You can then email just the link.
- Rename files before sending: In the Files app, tap and hold a photo, choose Rename, and give it a descriptive name. This helps the recipient organize the files.
- Check the attachment count before sending: Scroll to the bottom of the email body and count the thumbnails or file icons to make sure all photos are included.
- Use AirDrop for nearby recipients: If the recipient is nearby, AirDrop is much faster and has no size limit. Select photos, tap Share, then tap the person’s device.
Troubleshooting
- Email fails to send with “Attachment too large”: Reduce the photo size (choose Medium or Small when prompted), or compress the photos into a ZIP file. If that still exceeds the limit, use a cloud link instead.
- Photos appear as blank attachments: This usually means the original files are still in iCloud and not downloaded. Open the Photos app, tap the cloud icon on each photo to download it, then try again.
- Mail app crashes when attaching many photos: Close Mail completely (swipe up from the app switcher), restart your iPhone, and try again with fewer photos. If it still crashes, use the Files app method instead.
- Recipient says they can’t open the files: If you sent HEIC files (iPhone’s default format), the recipient may not be able to view them on Windows or Android. Change the format in Settings > Photos > Transfer to Mac or PC to Automatic, which converts to JPEG when sending via Mail.
- Share sheet doesn’t show Mail: Scroll to the far right of the app row and tap More. Toggle Mail on. If it’s already on, try restarting the device.
Frequently Asked Questions
Why does Mail only let me attach 5 photos?
Mail doesn’t have a strict limit of 5 photos. The confusion comes from the fact that when you tap the camera icon inside a new email, you can only select one photo at a time. To attach more, you must start from the Photos app and use the Share button.
Will my photos lose quality when sent by email?
Only if you choose a resized option (Small, Medium, or Large). If you select Actual Size, the recipient receives the original file with no quality loss. However, the file size will be much larger.
Can I send 100 photos at once?
Technically yes, but the email will almost certainly exceed the 25 MB attachment limit of most providers. For 100 photos, create a ZIP file or use a cloud sharing link instead.
Why are my photos sent as HEIC files instead of JPEG?
iPhones store photos in HEIC format by default. When you email them as Actual Size, they stay in HEIC. To send JPEG automatically, go to Settings > Photos > Transfer to Mac or PC and select Automatic.
Can I send photos from my iPad the same way?
Yes, the steps are identical on both iPhone and iPad. The only difference is the screen size and the location of the Share button (bottom-left on iPhone, top-right on iPad in some views).
What if the recipient never receives the email?
Check your Sent folder to confirm it was sent. If it shows as sent, ask the recipient to check their spam folder. Large attachments sometimes trigger spam filters. You can also try sending a smaller test email to verify your connection.
